Phase MID-V35-HOTPATH-OPT-1 complete: +7.3% on C6-heavy

Step 0: Geometry SSOT
  - New: core/box/smallobject_mid_v35_geom_box.h (L1/L2 consistency)
  - Fix: C6 slots/page 102→128 in L2 (smallobject_cold_iface_mid_v3.c)
  - Applied: smallobject_mid_v35.c, smallobject_segment_mid_v3.c

Step 1-3: ENV gates for hotpath optimizations
  - New: core/box/mid_v35_hotpath_env_box.h
    * HAKMEM_MID_V35_HEADER_PREFILL (default 0)
    * HAKMEM_MID_V35_HOT_COUNTS (default 1)
    * HAKMEM_MID_V35_C6_FASTPATH (default 0)
  - Implementation: smallobject_mid_v35.c
    * Header prefill at refill boundary (Step 1)
    * Gated alloc_count++ in hot path (Step 2)
    * C6 specialized fast path with constant slot_size (Step 3)

A/B Results:
  C6-heavy (257–768B): 8.75M→9.39M ops/s (+7.3%, 5-run mean) ✅
  Mixed (16–1024B): 9.98M→9.96M ops/s (-0.2%, within noise) ✓

Decision: FROZEN - defaults OFF, C6-heavy推奨ON, Mixed現状維持

Fix MID v3.5 activation bugs: policy loop + malloc recursion

Two critical bugs fixed:

1. Policy snapshot infinite loop (smallobject_policy_v7.c):
   - Condition `g_policy_v7_version == 0` caused reinit on every call
   - Fixed via CAS to set global version to 1 after first init

2. Malloc recursion (smallobject_segment_mid_v3.c):
   - Internal malloc() routed back through hakmem → MID v3.5 → segment
     creation → malloc → infinite recursion / stack overflow
   - Fixed by using mmap() directly for internal allocations:
     - Segment struct, pages array, page metadata block

Performance results (bench_random_mixed 257-512B):
- Baseline (LEGACY): 34.0M ops/s
- MID_V35 ON (C6):   35.8M ops/s
- Improvement:       +5.1% ✓

Phase v11a-3: MID v3.5 Activation (Build Complete)

Integrated MID v3.5 into active code path, making it available for C5/C6/C7 routing.

Key Changes:
- Policy Box: Added SMALL_ROUTE_MID_V35 with ENV gates (HAKMEM_MID_V35_ENABLED, HAKMEM_MID_V35_CLASSES)
- HotBox: Implemented small_mid_v35_alloc/free with TLS-cached page allocation
- Front Gate: Wired MID_V35 routing into malloc_tiny_fast.h (priority: ULTRA > MID_V35 > V7)
- Build: Added core/smallobject_mid_v35.o to all object lists

Architecture:
- Slot sizes: C5=384B, C6=512B, C7=1024B
- Page size: 64KB (170/128/64 slots)
- Integration: ColdIface v2 (refill/retire), Stats v2 (observation), Learner v2 (dormant)

Status: Build successful, ready for A/B benchmarking
Next: Performance validation (C6-heavy, C5+C6-only, Mixed benchmarks)
